●
Pre-collision braking
*
: Applicable to vehicles designed for regions that detection of pedestrians and/or bicy-
clists is possible (

P.285)
The system may not operate in the following situations:
●
If a 12-volt battery terminal has been disconnected and reconnected and then the vehicle
has not been driven for a certain amount of time
●
If the shift position is in R
●
When the VSC OFF indicator is illuminated (only the pre-collision warning function will
be operational)
■
Object detection function
The system detects objects based on their
size, profile, motion, etc. However, an object
may not be detected depending on the sur-
rounding brightness and the motion, pos-
ture, and angle of the detected object,
preventing the system from operating prop-
erly. (

P.292)
The illustration shows an image of detecta-
ble objects.

strongly.
●
The steering wheel is turned sharply or
abruptly.
■
Conditions under which the system may
operate even if there is no possibility of a
collision
●

the system may determine that there is a

ate.
